Technical progress of rotary flash dryer
Rotary flash dryer has been applied to various industries such as chemical industry, food, medicine, building materials, feed, etc. There are also many domestic manufacturers of rotary flash dryers, but most of the products are similar, and technological progress has been slow in recent years.
Recently, Shenyang Yitong Venture Company has developed a new type of drying equipment--ultra-fine powder dryer. This kind of drying equipment can be said to be an alternative product to rotary flashing. It is a multi-functional drying system integrating drying, crushing and grading. machine. The superiority to rotary flashing is that the crushing capacity of this equipment and the ability to process materials with secondary agglomeration can dry materials that cannot be dried by the rotary flash dryer and can be used for ultrafine and nanoscale particle sizes. Drying of strictly required materials.
At present, the machine has been successfully applied to the drying of materials such as nano calcium carbonate, nano aluminum hydroxide, micro powder aluminum hydroxide and nano magnesium hydroxide. Has already opened the prelude to industrial applications.
The basic working principle of the ultrafine powder dryer is the high crushing ability of the high-speed stirrer, and the classifier's control of the particle size of the material and the re-crushing effect of the secondary agglomerated material. The use of the swirling airflow and the material particles produces a great deal of Relative movement, thus strengthening the principle of heat and mass transfer to complete the drying of the material. Its unique advantages are the bottom-mounted high-speed crushing device and the top adjustable grading device, which can easily control the product's particle size; its structure is more advanced and maintenance and maintenance are more convenient. So that nano-ultrafine powder dryer has a stronger crushing and dispersing ability, and is very suitable for the drying of ultrafine materials.
